Solitary Wave Solutions of the High-order Nonlinear Schr?dinger Equation in Dispersive Single Mode Optical Fibers

摘要

The dynamics of propagation of waves in the transmission supports as high-nonlinear and dispersive optical fibers is governed by Schr?dinger equations that integrate supplementary nonlinear terms. This particularity complicates the resolution of this equation. So the resolution of such an equation requires a suitable method. In this article, we construct solutions of the type solitary wave by means of a method which supposes from the onset that the equation admits a solution that is a combination of the bright soliton and dark soliton and thereafter proceed by elimination of the constants until the exact solutions or those that are nearer to the exact solutions are obtained.
